UNITED STATES PATENT EEICE N. NV. VILLIAMS, OF FRANKFORD, PENNSYLVANIA,ASSIG'NOR, BY MESNE ASSIGNMENTS, TO HIMSELF.

IMPROVED LAM P-BURNER..

Specification forming part of Letters Patent No. 35,860, dated July 8,ISC-2.

To all whom it may concern.-

Be it known that I. N. W. WILLIAMS, of Frankford, (Philadelphia,)Pennsylvania have invented an Improvement in (loal-Oil-Lamp Burners;and I do hereby. declare the following to be a full, clear, andexactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention consists in certain improvements(fully. describedhereinafter) in the burners of coal-oil lamps, said improvements beingmade with the view of dispensing with the usual glass chimney,preventing the smoke and disagreeable smell, and avoiding the complexpassages and other appliances common to this class of coal-oil lamps.

In order to enable others skilled in the art to make and use myinvention I will now proceed to deseribeits construction and operation.

On reference to the accolnpanying drawings, which form apart of thisspecication, Figure l is a vertical section of my improved coaloillampburner; Fig. 2, an exterior view of the cap, and Fig. 3 a sectional planofthe same.

Similarletters refer to similar parts throughout the several views.

A is a cover screwed into the ,orifice at the top of the reservoir B,containing the coal-oil, a portion only of this reservoir being shown inthe drawings.

Through the cover A, which is hollow,p asses the spindle C, on which arethe usual wheels for raising and lowering the at wick in the tube D, thelatter being secured to the cover. This tube is carried upward to agreater length than those of ordinary lamps,and is surrounded by theelongated casing or cap E, the lower end, e, of which is enlarged andmade flaring, so as to overhang the cover A, the rounded top having theusual oblong opening. The' casing E is connected tothe wick-tube D bymeans of the strips 11, which are eut from the sides of the cap, bentinward, and notched at the ends, so as to :lit to the opposite edges ofthe wick-tube to which they may be soldered, thereby maintaining thecasing in its proper position in respect to the said wick-tube.

In coal-oil-lamp burners as heretofore constructed for the purpose ofdispensing with the ordinary glass chimney, chambers for heating the airadmitted through perforatious and contracted passages for directing theheated air to the amehave been deemed indispensably necessary to preventsmoke and the disagreeable smell which generally accompany the flame ofcoal-oil lamps.

I have found, after many experiments, that the most thorough consumptionof smoke can be effected by the simple elongated casing or cap E,between which and the Wick-tube is presented a chamber, F, the latterbeing entirely open below and presenting no obstruction to the freeentrance of a plentiful sup.- ply of air, the progress of the latterupward being uninterrupted saving by the bentstripst' ,which occupy tooinsignificant aspace within the chamber to arrest the current of airthrough the same.

The air admitted without stint or obstruction below becomes heated inthe chamber F, and rushes with such force through the oblong openingf incontact with the tiame as to cause the latter to burn with brilliancyand unaccom'panied with the usual smokcand disagree- The liame of thelamp, too, may be reduced in extent without becoming extinguished, whichis the result of a reduction of the fiame of ordinary lamps; hence myimprovement is 'especially applicable to lamps required for night use.

The covers of coal-oil lamps are generally so loose as to allow more orless leakage of theV gases generated in the reservoir, these gasescausing a disagreeablesmell, which is avoided i by my improved burner,the lower end of the exterior casing, E, being flared and overhangingthe cover, so that all vapors passing from the reservoir at the point mwill be carried with the air through the. chamber F and consumed bytheflame.

As regards the construction of my improved burner, it will be seen thatit is of the most simple and inexpensive character compared with otherburners7 in which the complex passages and appliances hitherto deemednecessary for a thorough consumption of the smoke demand tediousmanipulation to manufacture and great care to adjust and maintain inproper order.

I claim as my invention and desire to secure by LettersPatent- 1. Theexterior casing, E, with its oblong openingf, in combination with theelongated Wick-tube D, when so arranged and connected together as toleave an unobstructed opening below for the free ad mission of air tothe chamber between the easing and tube7 as set forth, for the purposespecified.

2. Flaring the lower end ofthe casing E so as to overhang the cover Aand permit the gases passing from the reservoir at the point where thecover is secured to the same to pass upward into the chamber l), as setforth.

3. Securing the exterior casing to the Wicktube by means of strips i,bent from and forming part ofthe said casing, as specified.

In testimony whereofI have signed my name to this specification in thepresence oftwo sub-4 scribing witnesses.
